Positive solutions to a second order multi-point boundary-value problem

Daomin Cao & Ruyun Ma
Abstract:
We prove the existence of positive solutions to the boundary-value problem ,
where
is a continuous function that may change sign on [0,1],
is a continuous function with
, and
is a samll
positive constant. For finding solutions we use the Leray-Schauder
fixed point theorem.
